Effects of RS4 type resistant corn starch on the quality characteristics of cookies were investigated by physicochemical, instrumental and sensory evaluation. The resistant starch was made by cross-linking of corn starch as following; corn starch slurry was annealed at pH 2.0 and $50^{\circ}C$ for 2 h followed by the cross-linking reaction. The cross-linking reaction was performed at $50^{\circ}C$ for 12 h in the presence of 1.2%/st.ds NaOH, 10%/st.ds sodium sulfate and 10%/st.ds of sodium trimetaphosphate (STMP)/sodium tripolyphosphate (STPP) mixture. Dietary fiber content of the resistant starch was estimated to be 73.8% by the AOAC method. For quality characteristics, dough pH decreased with the increase of the resistant starch content and spread factor decreased a little at 20% of the resistant starch. The moisture content and L value of cookies increased with the increase of the resistant starch content. However, the hardness and fracturability decreased with the increase of the resistant starch content. In the sensory evaluation, no significant differences were observed between the two cookies with or without the resistant starch. The results of this study suggest that the RS4 type resistant corn starch can be a good ingredient to increase dietary fiber content in cookies without changes of their qualities.

In a product environment where various product-service systems (PSSs) are already being provided, the provision of a different type of PSS is difficult for second movers but necessary for their sustainability and differentiation. Despite the importance of providing distinguishing PSSs to market, prior PSS studies have not effectively considered the influence of existing PSSs in their methods. In response, we suggest an approach to generate new PSS concepts by employing general needs (GNs) and business system evolution patterns (BSEPs). Our approach 1) identifies customer GNs fulfilled by existing PSSs, 2) generates advanced PSS ideas from an evolutionary perspective by mapping the existing PSSs onto BSEPs, and 3) selects PSS ideas that can meet the unfulfilled or insufficiently considered GNs using a GN-PSS linking matrix, thereby generating new PSS concepts based on the selected ideas. The workings and practicability of this approach are illustrated using a PSS case study of furniture industry. This approach would provide PSS planners with an ability to generate the differentiated PSS concepts that handle the customer needs that have been untapped throughout a product's lifecycle. In addition, this approach as a module will have a synergetic effect when incorporated with other PSS methodologies.

The service quality and image are a central factor in understanding tourists destination choice. Existing literature suggests that sport event and destination image could interact to influence tourism behaviours. The purpose of this study w as to identify the factors influencing local image and re-visit intention in the 68th Chungcheongnam-do Provincial Sport Event held in Yesan city. The results of the study are as follows; First, as a result of factor analysis on the satisfaction with the sports event composed of 17 items, three factors were categorized, which were 'event management', 'event facility' and 'supporting facilities'. Second, satisfaction with local event had a positive effect on local image. Especially, satisfaction with event management had greater effect on local image than event facilities and supporting facilities. Third, as satisfaction with local event had positive effect on re-visitation intention, satisfaction with sports event had positive effect on the success of the sport event itself and re-visitation intention for the region. Fourth, as local image had a positive effect on re-visitation intention, strategic approaches to linking factors of tourism are required to attract visitors in addition to sports events.

In the 4th Industrial Revolution, the healthcare industry is undergoing a paradigm shift from post-care and management systems based on diagnosis and treatment to disease prevention and management based on personal precision medicine. To optimize medical services for individual patients, an open ecosystem for the healthcare industry that allows the exchange and utilization of personal health records (PHRs) is required. However, under the current system of hospital-centered data management, it is difficult to implement the linking and sharing of PHRs in practice. To address this problem, in this study, we present the design and implementation of a patient-centered PHR platform using blockchain technology. This platform achieved transparency and reliability in information management by eliminating the risk of leakage and tampering/altering personal information, which could occur when using a PHR. In addition, the patient-consent system was applied to a PHR; thus, the patient acted as the user with ownership. The proposed blockchain-based PHR platform enables the integration of personal medical information with scattered distribution across multiple hospitals, and allows patients to freely use their health records in their daily lives and emergencies. The proposed platform is expected to serve as a stepping stone for patient-centered healthcare data management and utilization.

Purpose : This study was done to examine the home care service provided by home care nurses and the level of client satisfaction in community. Method : Data were collected from 120 clients who received the home care service at the community home care service center in Pusan from 2th May. 2003 to 31th May 2003. The tool for measurement of satisfaction was composed of 16 items and was 4 score scale by Kim. Data were analyzed by using SPSS/WIN 10.5 program. Result: 1) 67.5% among 120 clients was over sixty years old and 30.6% of clients received home visits 20 times by home care nurse. 2) The total number of home care services was 15,783. And most of the clients received therapeutic nursing care. 3) The mean score of satisfaction on provided home care services was 3.31, among 16 items, "The home care nurses kept up the secret of patients and family" was the highest($3.67{\pm}0.48$). the total level of satisfaction of home care services was very high, with mean score $3.31{\pm}0.32$. Conclusion : The satisfaction level of home care services was very high. so we can expect that the prospect of home care services is very challengeable. Therefore we should try to expand the service recipients with promotional education to assure close ties with the public health centers for the continuous home care service linking and make more efforts to improve the quality of the service.

O2O(Online-to-Offline) commerce, a kind of multi-channel, is used in various industries such as accommodation, food and beverage, transportation, and real estate. The O2O commerce, a channel of integrating online and offline, overcomes the limitations of traditional online commerce, where a customer made a purchase decision without direct experience. Despite this advantage of O2O, if the online-offline channel is not effectively linked, customer's complaints would occur due to service failure. This study, with regard to O2O service failure circumstances, intends to investigate the effect of customer's perceived justice on their emotional response, recovery satisfaction, followed by intention to repurchase. Perceived justice in this study is composed of distributive justice, interactional justice, and procedural justice. Furthermore, this study explores the moderation effect of O2O industry types in the relationship between perceived justice and emotion. An O2O industry type is classified into accommodation, food and beverage, and transportation. A hypothesized research model was empirically tested using a structural equation model. The current study collected 433 questionnaires and the target respondents are customers who have experienced service failure in O2O commerce. The empirical results showed that O2O commerce more effectively conducts service recovery strategy and causes positive customer response by integrating online and offline channel. One of the ultimate purposes of O2O service providers is to reduce the likelihood of service failures and to recover more quickly and efficiently by linking two channels rather than using a single channel. This study suggested that the O2O channel is effective in influencing customer satisfaction and loyalty by inducing customer's positive emotions in recovering service failure.
